NTDOOM

NTDOOM is a minimalist port of the Linux Doom source code to the platform, specifically targeting early  versions (official support is stated for NT 4). It was ported by Petteri Kangaslampi. The earliest apparent release was on January 7, 1998 (via archive.org) and file timestamps suggest work on the port started as early as January 4, only 12 days after the release of the Doom source code. The last release was dated January 29, 1998, when the port was discontinued as its stated purpose had been accomplished.

It can be compiled using either or. It uses a custom audio library written by the same authors called the Housemarque Audio System.

The port was intended only as a basic translation of the Linux source release to Windows, to serve as a basis for other ports, and as such it was not developed or supported any further once it was functional at a basic level. Together with ATB Doom, it became part of the foundation of the advanced ZDoom source port.
